When the bugrat dared the girls to attack him Gwazi simply grinned. With a sudden force of strength he pushed himself free of the pin long enough to swing his sword at the arm the bugrat would have used to pin him in place. Then once Gwazi dropped to the ground being free of the bugrats grasp he simply said "You asked for it" before ducking and rolling underneath the bugrat and piercing the sword right into his gut from underneath. Hopefully that did some decent damage to the bugrat and would keep it in shock for at least a few seconds, but at the same time Gwazi just left himself in a very vulnerable position. One the Bugrat could easily exploit of the girls don't follow up and cover him.
